If our stomachs remind us of themselves by some misbehavior we must seek for the cause and remedy it, but we should not on any account feel that the cause is necessarily in the food we have eaten.

It may be, and probably often is, entirely back of that.

A quick, sharp resistance to something that is said will often cause indigestion.

In that case we must stop resisting and not blame the food.

A dog was once made to swallow a little bullet with his food and then an X-ray was thrown on to his stomach in order that the process of digestion might be watched by means of the bullet.
